Go to bad ideas > Ka-****ing-Boom, and they have smoke bomb plans (as well as about a hundred other real bomb plans).
You need KnO3(Potassium Nitrate, AKA Salt Peter), and sugar. I think its a 60/40 mixture of KN03 to Sugar. Mix it up, then melt it in a double boiler.
When it starts steaming, its done. Dont light it on fire. Do this on low heat. USe a hot plate if you can.
While its still molten, put a fuse in it.
You can even make a mold, pour it in, and then put the fuse in.
