In a medium skillet, over medium heat, add enough oil to reach a depth of 1/2-inch. Heat the oil until a deep-fry thermometer registers 350 degrees F, or when the end of a wooden spoon sizzles when dipped into the oil.
Working in batches so as not to crowd the pan, dip the fish strips in the beer batter and coat on both sides. Let the excess batter drip off, then fry the fish in the hot oil until golden brown and cooked through, about 2 minutes per side. Transfer to a plate lined with paper towels to drain.
Smear each tortilla with a generous amount of the chipotle sauce, then top with the cabbage slaw. Lay one piece of fish inside each tortilla and serve with lime wedges. Or pico de gallo and fry sauce.
