In a gallon-size Ziploc bag, combine vinegar, soy sauce, olive oil, cumin, black pepper, salt, garlic powder, chili powder, paprika, onion powder, oregano, lime juice, and minced garlic.
Add flank steak to the marinade and mix really well to guarantee all surfaces are coated.
Seal the bag and marinate for at least 6 hours, preferably overnight in the refrigerator.
Preheat grill to medium-high heat.
Remove steak from marinade and grill until desired degree of doneness.
Let steak sit for at least 5-10 minutes after grilling.
Once the meat has cooled, slice across the grain into small chunks.
Warm tortillas and serve with sliced carne asada and toppings of choice.
