Small blind play in tournament when everyboy else has folded

[thenlguru]

I have major leak in my game, I dont have even the tiniest clue how to play in SB when everybody else has folded.
I fold 90% hands here, and usually call the other because I just hape putting fair share of my stack in to the pot out of position. Only exception is when the BB is very short stack and I can push around by putting him allin.

I dont know how to specife my question, but if someone have general advices for SB play in tournament I would be very thankfull!
