Try stealing the blinds when the antes are in. You can do this with air basically (you don't need a "real" hand), but beware of the players you are trying to steal from. If they are thinking players, they will probably have noticed you have not played in a while and might put you on a very tight range when you open (even from late position), so they will probably not defend lightly. That being said, even if you don't hit the flop when they defend, you can represent a strong range and take down the pot with a cbet.
Also, try stealing if the SB and BB players are tight (again, air against tight should work), but if a tight player defends, think twice before cbetting.
