Depends upon the finish. Hopefully the smoke is on the surface and didn't get into the finish material.
If it was mine, I would disassemble it and remove all the hardware.
Then I would wash it with Naptha thoroughly.
Finally (if its a gloss finish) I would polish the whole guitar to strip off a small layer of finish using a polishing compound wheel like a auto polisher (not wax buffer).
