Telekinesis, assuming I'm only allowed one power. Otherwise I'd go with something more vague like "Psychic powers" which would include telekinesis, mind reading, the old jedi mind trick, minor fortelling of the future, and whatever else is attributed to psychics.
Why? Because TK is basically a green lantern ring. You can do a LOT of very diverse things with it, with so few limitations that it might as well be only limited by your imagination. The other psychic powers are just gravy.
