Drain and rinse the canned jackfruit, then use a fork to shred the pieces into a meat-like consistency.
Finely chop the seitan and rehydrate the soy curls in warm water for 10 minutes before squeezing out excess moisture.
Heat the olive oil in a large skillet over medium-high heat and add the shredded jackfruit, seitan, and soy curls.
Stir in the adobo sauce, garlic powder, sea salt, and black pepper, sautéing for 5 minutes until the edges are slightly crisp.
Pour in the water and black beans, then reduce heat to low and simmer for 8 minutes until the liquid has mostly evaporated.
While the filling simmers, blend the avocado, nutritional yeast, and lime juice in a small processor until completely smooth.
Warm the corn tortillas in a dry pan until pliable and slightly charred.
Assemble the tacos by dividing the jackfruit mixture among the tortillas and drizzling generously with the avocado crema.
