Combine water, broth, chicken, 1/2 of the cauliflower, 1/2 of the celery, onion, garlic, cayenne, garlic powder, seasoned salt, cumin, black pepper, and bay leaves in a large stockpot. Bring to a boil; reduce heat and let simmer until chicken is cooked through, about 20 minutes.
Remove chicken and shred with 2 forks.
Remove stock from heat and puree with an immersion blender. Add shredded chicken, soybeans, mushrooms, baby corn, red peppers, and lime juice to the pot and stir to combine. Return to a boil; reduce heat and let simmer for 1 hour. Serve.
