Brown ground beef in a skillet over medium-high heat, seasoning lightly and letting it sit undisturbed before stirring.
Drain excess fat, keeping a small amount behind for flavor.
Sprinkle chili powder, cumin, garlic powder, onion powder, smoked paprika, oregano, salt, and pepper over the meat and stir to coat.
Whisk beef broth, tomato paste, and cornstarch together, then pour into the skillet.
Simmer for 3-5 minutes until the sauce thickens and clings to the meat.
Warm tortillas over a flame or in a dry skillet until pliable.
Fill tortillas with taco meat and desired toppings, then serve immediately.
