Dry brine the salmon over night in a kosher salt/brown sugar brine on a cooling rack in a pan.
Rinse off and pat dry the salmon and smoked the next day with your smoker set in about 180 degrees until your salmon reaches the proper internal temperature.
Once it is done let it cool to room temperature. Pack all the fillets in brown paper lunch sacks. Probably best to double or triple pack them the first day.
Store these in your refrigerator for several days changing out the paper bags once the old ones have greased through.
After 5 or 7 days you will end up with a very jerky like product.
I have some in my fridge right now.

This is the last of a batch made about a week before Christmas. It stores a very long time. The longer you store it, the more jerky like it becomes
