find things to do with your hands
knitting was a good suggestion, but not one you'll generally get out easily in public.

I've known people to use

eating chuppa chups (turned into an even more expensive habit)

learning to juggle

hacky sack

any small kind of ball or toy you can roll around your fingers or play with when you feel lke a cigarette or see other people smoking.

You quit the nicotine while still retaining the habit. Hopefully gaining a new skill in the process.

Good luck
