There have been a lot of good suggestions about sealing the chamber, adding mass or tuning plates, and running the offset with the vent open. The biggest issue I see with that model is that the only way to feed the fire is through the door on the top of the fire box thus allowing all of the smoke and heat to rise out of the top of the fire box and not flow through the chamber.
Fire is controlled by three things heat, fuel, and air. to control the heat you have to control one of the two other things. From my experience a vertical charcoal smoker like a Weber Smokey Mountain runs best when controlling air flow. The Minion method or a charcoal maze does this well. A stick fire like it sounds you are using works best by limiting fuel and allowing the fire to have as much air as possible. So typically you would open the chimney fully open and the side vent of the fire box would be fully open. This allows the smoke to flow through the cooking chamber.
I would consider widening and adding a door to the side of the fire box that is large enough to feed fuel to the fire and add fuel as needed to maintain the right quality of smoke and heat. Get a pair of fire gloves or a fire place tool kit to help manipulate the coals and grab your drink of choice and enjoy. Unless others have suggestions this is not really a set it and forget it setup but it makes some amazing BBQ and is a lot of fun.
I would spend half an hour and watch Aaron Franklin's episode on fire and smoke. It has a lot of good tips about using an offset smoker with sticks.
