Moonlight Stalker is a great feat if you had your heart set on taking Blind Fighting anyway.

I have a PFS character with Keen Scent, Blind Fighting, and an Eversmoking Bottle. The problem is most of the rest of the players don't have see-while-blind techniques sorted out, and they usually resent it when I open the bottle, even when the situation is called for. But if the whole party is on board, it is a devastating tactic.
Eversmoking Bottles are made with the Pyrotechnics Spell. Pyrotechnics is a very good choice, too.

An Eversmoking Bottle. Your only problem will be Ifrits who have the Firesight feat.
Some of the oracle mysteries also have vision which penetrates smoke.
It is possible to use smoke and a level of oracle of flame to make a rogue (or vivisectionist) who can make multiple sneak attacks in one round, but I've only theory-crafted the idea.
