Preheat oven to 475 degrees. Line baking sheet with aluminum foil; brush with oil and set aside. Stack tortillas and wrap in foil. In a large bowl, stir together yogurt, cilantro, lime juice, and hot sauce; season with salt and pepper. Add cabbage and jicama and toss to combine; set aside.
Season fish with salt and pepper. Beat egg in medium bowl. Place bread crumbs in a shallow dish. Dip strips of fish in egg, then bread crumbs, pressing crumbs onto fish to adhere. Arrange fish strips on prepared baking sheet and drizzle with 1 tablespoon oil. Bake until golden brown and opaque throughout, 15 to 18 minutes. After about 6 minutes, place tortillas in the oven to warm.
While fish and tortillas bake, cook beans, cumin, and chili powder in a small saucepan over medium until warmed through, 4 to 6 minutes; season with salt and pepper. Set beans, tortillas, cabbage mixture, and fish on table, and let each diner build his or her own taco.
