Make marinade. In a small bowl, whisk together the soy sauce, lime juice, orange juice, minced garlic, diced chipotle peppers, 1 teaspoon salt, chili powder, cumin, oregano, and ½ teaspoon pepper.
Marinate. Using a 2-gallon Ziploc bag or a casserole dish, place steak and marinade in the bag or dish completely covered and sealed. Marinate in the fridge for 1 to 4 hours, turning the steak to the other side halfway through. (If you only marinate for an hour, you can keep it at room temperature).
Season with salt and pepper. 30 minutes before cooking, remove the steak and place it on a cutting board. Pat dry with a paper towel and sprinkle both sides with the remaining 1 teaspoon of salt and 1 teaspoon of pepper. Let it sit at room temperature for 30 minutes.
Prep for cooking. Preheat the broiler (most ovens are about 500 degrees Fahrenheit.) Place steak on a baking sheet (optional: line with foil for easy cleanup).
Broil. Broil the steak about 5-6 inches from the heat for 7 minutes on each side. Remove from the oven, tent with foil, and let sit for 10-15 minutes before slicing.
Warm tortillas. Wrap tortillas in damp paper towels, place on a large plate, and microwave for 20-30 seconds in the microwave.
Slice. With a sharp knife, thinly slice the steak at a slight angle against the grain.
Serve. Place a few steak slices in a tortilla and top with desired toppings to serve. Serve warm.
