Spray a large casserole dish with cooking spray and set aside.
Meanwhile, cook beef and onion in a large skillet over medium-high heat until meat is no longer pink. Drain.
Drain ½ cup of liquid from the tomatoes. Pour the tomatoes and any remaining liquid from the can into the skillet with the beef.
Stir in the cooked rice, garlic, Worcestershire sauce, curry powder, salt, onion powder, and pepper.
Pour the mixture into prepared dish. Top with bacon.
Bake at 375 degrees until bacon is crisp and casserole is bubbly (about 25-30 minutes).
