Here's what I do for turkeys. I line the bottom of the basket with one layer of unlit coals, either briquettes or lump works the same way. Then I put 3 or 4 chunks of wood on top of that. Then I dump a whole chimney of lit coals on top of that. It will blow white smoke for 10-15 minutes, then it's clear blue for the 4 hours or so it takes to cook a 12-15 bird at 325˚-375˚.
If I'm doing the Minion method, I'll do the same thing with the one layer of coals and put 3 or 4 chunks around the outside of the basket. Then I'll fill the basket with unlit and remove coals from the middle to form a well. An empty coffee can with both ends cut out helps also. I'll drop a chunk at the bottom of that well, and then top off with 10-15 lit coals.
The idea is you want your chunks covered so they're not getting a free supply of air.
