Depending on whether your gingerbread project will be eaten or for display only (or must follow certain rules of a competition), there are several methods for creating chimney "smoke." Your choice of smoke also depends on how charming or realistic you wish your smoke to be.
I have piped royal icing "swirls" of smoke as a lattice shape on wax paper, removed it, then glued the swirls to each of the insides of the chimney. Cotton candy or real cotton. For a few minutes of great display, create a well in the chimney using aluminum foil--then insert dry ice. Hi-peaked egg whites. Edible clays molded into dramatic smoke formations. Taffy candies that are sold as swirls.

Cotton Candy is the most common "smoke" I've seen used on gingerbread houses. Let us know what you try and how it turned out.
