Firstly, go early, when they are checking ID's but there isn't a line (or even before the are checking ID's, but there and just hanging out).
I open them, like I would a girl, at least when I'm up in line, or possibly sooner if I see a situational opener.
And then I just start a conversation.
Situational is best, saying something funny about something going on, or just awareness of someone doing something out of place (like someone being drunk and stupid).
I also did this in my recent field rapport when I came to a new venue and a girl was hitting a juul. Take a look if you haven't already
If nothing situational I'll ask them how the night is going, I may say it's my first time there or I just started coming there and ask when it gets good (which also sets the stage for a longer conversation, since I'm "new"), and more or less try to hook them then and there (maybe saying something like "When do the girls who want to make mistakes get here? Like the ones who want to make a bad decision?" - Used that in the past to success but haven't in a while, haven't had to).
If there is no hook because they are busy or in a bad mood or whatever, I'll make a mental note and just circle around to them later. I'm pretty sure
@Skills mentions offering to or just grabbing them a water later. Personally I'll just float back around and find an excuse to talk to them i.e. I need a stamp to get back in and ask them if they'll remember me, thus can I do it without a stamp (turn a bit close to them "I don't want my girlfriend to know I was out here picking up chicks" said with a smirk, just something funny like that). But better is if something happens out front or in line and I will just look at them, make eye contact like and an expression of "can you believe that!", comment on the situation etc.
Also, I look at it as essentially having to close the bouncer, so if don't get anything really good going with a girl, I still consider the night a success if I feel I made a connection there (which to me, on a first night out, would be that they remember me and we exchanged names, as a minimum).
For a really strong hook, like I had on Wednesday, I'll chat with the bouncer and anyone else around (in this case the hostess), and then actually just hang out there as people start coming in. I'll even start opening the cute girls in line, a lot of times taking their ID's (if you're just standing with the bouncer, a lot of times they assume you work there. Could just be part of my persona, decently built and professional, but either way you can joke with them and/or take ID's), and of course after I check their ID's and make a comment on it (On Wednesday I made a cute blonde pronounce her god awful last name, and then said "Whatever, if you say so" as if it was a fake name from a fake ID and she was making it up lol).
And, I think it is obvious to a guy like you Glow, but anyone else reading this, this is an easy way to get some sets started for the night, particularly if you're going out solo (not to mention get some social and sexual momentum, sexual from the flirting).
But to the point of the minimum (name close, will remember me) on a first night at a new venue (or a first night seeing a new bouncer), if nothing else, when I leave I make a point to thank them, tell them it's a good place, that I'll be back, ask their name, shake their hand and tell them to have a good night.
Further, I'll go to the same place again the next night in particular if I had a weaker close in order to lock it down, it's much easier to become known if they see you Friday night and then Saturday night for example. With a solid close (like Wednesday), I may move on to another venue altogether as I lock down the area. Also, this assumes you're scouting venues or have a good idea this is a place locking down, I'm almost certain Teevster mentioned scouting 2 or 3 new places one night while becoming accustomed to a new area in one of our two "Teevster and Watts discuss" threads, although for some reason I couldn't find it (those threads may be a worth a look anyway). Although, I may also make it a point to get to one venue early, before they even convert to "nightlife", and commit to staying the whole night (or pulling, even better! haha), just to understand the flow of things. Sometimes a particular bar will become great at a certain time, or it will be too crowded past a certain time, so that may be worth knowing.
I will also write down the position, name, physical description and short summary of what we talked about or anything of note that happened in my Evernote. That way I can check it before seeing them next time (in the uber, on the way).
Described that here:
Hi beginner here I've been studying game for a year-and-a-half now. even though I made a lot of strives and a lot of progress it's not at the pace that I want. (By that I mean I still haven't gotten laid or been on dates). Now my first year I was completely clueless and it was so much...

Hope this was helpful!
Side Note: I used a variant of your "relaxed, expressive and enthusiastic" routine (what is congruent with me) Wednesday and Friday in my FR, from the
