I've been a member of a BBQ site for a few years now. Those folks have taught me a new way to cook food, to say the least.
Here's a link to the first time I smoked a salmon, complete with pictures.
There's also some "sides" in there, in case yo're interested.
I've done salmon a couple times since then, but honestly, I haven't been able to improve on that first endevour.
It takes some time, some patience, and an entire rack of your refrigerator for a couple days, but the results impressed the family.
Hope that helps.
Bob
