In a large bowl, use a fork to gently mash the tofu into bite-size pieces - not into a paste.
Using a large spoon, stir in the mayo, pickles, kale, celery, dill, and red onion.
In a separate bowl, whisk together the mustard, nutritional yeast, cumin, onion powder, garlic powder, turmeric, celery seed, tahini, lemon juice, and lemon zest.
Add the mustard mixture to the tofu mixture and stir gently to combine.
Cover and refrigerate 3 hours. Serve with toast.
