You're going to want super visual stuff, anything you can perform without talking is great for parties - stuff with complicated routines or patter won't go over well in a party environment where you might not be heard properly.
Coin tricks are great, I have a set of coins I have covered in glow paint for stuff when I do stuff at house parties and hookah bars and the like, just get some half-dollar sized coins (quarters aren't as visual) and go for it. Three Fly, Coins Across, and your various vanishes/productions are all fun. I'd recommend checking out the 'Mirage' vanish and 'Flicker' production here on theory11. They're just a really cool vanish/production combo that can add variety. A lot of vanishes look very similar, but Mirage really stands out.
Getting cards out isn't so bad, just get into the habit of keeping a deck in your pocket. Cut the side flaps off for easy removal, and you're good to go. Stuff like Transpositions, T&R, and color changes work the best for me because of their visual nature. I live in a multilingual part of Colorado and it's very helpful to be able to do magic that requires very little talking - this translates perfectly to a loud bar, club, or party.
Ideally you'll also want in-the-hands tricks, at a party or club there might not always be a lot of good working surfaces. Stuff like gambling demos and coin matrices you'll probably want to avoid save for rare exceptions.
Coins might be the best, but depending on how versatile your sleight of hand is it could be difficult to build a full routine around it (if you're a coin pro disregard this!) I might recommend a handful of card tricks too in case you start to run out of coin stuff.
