In a large bowl, combine the beef strips with garlic powder, onion powder, salt, and pepper. Mix well to coat the beef evenly.
Heat a large skillet or wok over medium-high heat. Add the beef strips and cook until browned, about 5-7 minutes.
Add the mixed vegetables to the skillet and stir-fry for another 3-4 minutes until the vegetables are tender-crisp.
In a small bowl, mix together the ketchup, mustard, Worcestershire sauce, and hot pepper flakes.
Pour the sauce over the beef and vegetables in the skillet. Stir well to combine and cook for an additional 2-3 minutes until the sauce is heated through.
Serve the spicy beef stir-fry hot, garnished with additional pepper flakes if desired.
