If wood chips is all that's available you could try putting them in aluminum foil and poking holes in it. I've never done this myself but someone else may chime in that has.
I've done this. Make a pouch with the foil, put in chips, close foil, and punch a bunch of holes in it with knife/fork. put on hot coals.
I bought a Smokey Joe the other day for the soul purpose of grilling steaks.:grin:
If it were me, and the SJ was my only grill, I'd try to bank the coals all to one side and go with a more indirect approach as to not dry out anything. (Except steaks. Those go right over the coals) Use half the briquettes your using, bank all to one side, put food and top exhaust on opposite side.
Might be interested in the bottom vent mod so you don't burn the hell out of your fingers, LOL:
