As I'm sure any non-smoker will attest, cigs smell alot more than tanned hide or human amino acids. I think I've run a pretty comprehensive test on this subject. Thorough enough for me anyway.
I carry a bar of unscented goat-milk soap with me, and wash my hands after I have a smoke. But sometimes I forget the soap, and the difference is definitely significant. I've seen the contrast in dozens of different waters, one of which I fish a dozen times, or more, per month. There's no question in my mind; smoky flies result in lower catch rates.
As far as materials in your house go, I guess you could try Febreeze, or Nilodor. I hate the stuff, but it works. An easier way, which I think would work fine, is to carry a little unscented soap, and wash your wets. Any good dry fly floatant (Aquel) is designed to also mask scent, and dries don't disperse smells through the water the way wets do anyway, so I think you're good.
For the future, if you continue to smoke in your house, consider sealing up all your materials. After enough years residue can really build up. My mother recently passed away, and we were cleaning a few things from her room. It can be really hard to get 15 years of cigarette smoke residue to come off of porcelain, let alone softer stuff, so forget about getting it out of hackle or deer hair.
