Pretty much anything will work, I find it best to present things casually though. Most of my stuff is light hearted/quick, card to wallet, card to pocket, card to mouth, deck to pocket. Once I've done some stuff like that for a bit I may move into a more serious 'psychological' presentation of mental magic, this mostly consists of key card, a peek or two and Out of This World. Bonus points for anything interactive.
Angle Zero is a great option too, though I don't like destroying cards much so I don't perform it loads, parties offer many great locations for reveals over many other circumstances, in your pocket, in your shoe, in the spectators pocket, inside a drink, on the wall, in a drawer, possibilities are endless.
I've never really had a 'set' of magic as the vast majority of my performances are done socially and at parties, this context is great for improvisation, people will be coming and going, may or may not be interested, whatever, just have some stuff ready to go.
