lot of variables...wsm temp, size of piece, desired amount of pink, exterior browning...
I might start with a 1/2 lb piece, salted and seasoned, try to almost cold smoke it for an hour or less, and then try searing in a dry pan or screaming hot fire. The goal would be a mostly pink piece, with some smoke, and a nice crust.
I'll dig through my notes and see if I recorded anything for that smoked tuna.
