Here is a hot and sour tofu that I am doing today from a recipe that I modified to make it a lot hotter...this is not a soup, but a dish that can be served over rice(Thai, of course) or noodles. Also I have included a Spinach & Tofu soup, so let the fun begin!

After the tofu has drained under a weight(I use a brick)cut it into one inch cubes. Heat the peanut oil in a wok and stir fry the tofu until it is browned, then remove and keep warm. Add the garlic, hab, ginger and the leek, cut into slices, and stir fry until fragrant, add the chile paste, soy sauce & vinegar and the retained tofu, and cook for about two minutes...if this is too thin, mix one tbls cornstarch with two tbls water and add slowly until the consistency suits you...finish with chopped leek greens and perhaps a dash of sesame oil, then serve, either over rice or noodles, or beside it, whichever.
