In a large bowl, combine ground brisket and minced garlic.
Shape the mixture into evenly shaped patties. Cover and chill in the refrigerator for at least one hour.
Fire up your smoker to 225°F (107°C) and add a handful of oak wood chunks to the coals. If you are using a grill, set up for 2-zone indirect cooking.
Season the brisket patties with kosher salt and black pepper
Place patties on smoker or grill grates (on the indirect side). Be sure to leave at least 1 inch of space between each patty.
Smoke until burger internal temperature is 140°F (60°C), about 1 hour
On the hot side of your grill (or in a cast-iron skillet over medium heat), cook the bacon for 2-3 minutes per side.
Sear patties either on high heat on your grill or in a hot cast-iron skillet. After 1-2 minutes, flip burgers and place cheese on top. Cook for a further 1-2 minutes, or until cheese has melted.
Serve when cheese is melted and burger internal temperature is 165°F (74°C)
Serve in buns, and top with bacon, lettuce, tomato, pickles, red onion, and barbecue sauce
