Cook bacon in a skillet over medium heat until crisp, 3 to 5 minutes.
Transfer to a paper towel-lined plate to drain; let cool and crumble. Reserve bacon drippings in skillet.
Combine crumbled bacon, potatoes, flour, eggs, garlic, thyme, salt, and black pepper in a large bowl.
Pour vegetable oil about 1/4-inch deep into skillet with bacon drippings and place over medium heat; heat until the oil and bacon drippings shimmer.
Gently drop potato mixture by heaping tablespoon into hot oil and flatten potatoes into small patties about 3 inches in diameter. Cook until browned, about 3 minutes on each side.
