I would follow the instructions on the kit. Cooked meat will still take on the smoke flavor, however, if you do plan on smoking it afterwards, if possible, run your smoker cooler so you don't "overcook" the meat with the additional heat that the smoker puts out. I don't know what smoker you have, but if you can, I would say open the lid or door a fair amount so its not too hot and smoke like the instructions on the kit say to. If no times are listed, depending on what smoker you have and what you have for wood, dust, chips or chunks, maybe smoke for 30-60 minutes. As long as you have some smoke going across the meat, it will take the smoky flavor.
