Arrange the tofu on a baking sheet and top with another baking sheet and several plates. Let stand for 1 hour to press out some of the excess water. Pat the tofu dry.
In a bowl, combine the wine, olive oil, mint and parsley and season with salt and pepper. Add the squash, zucchini, onion, pepper, tomatoes and tofu; let stand for 5 minutes.
Light a grill and oil the grates. Grill the vegetables in a grill basket over moderately high heat, turning occasionally, until tender, 10 minutes. Grill the tofu directly on the grates, turning, until charred all over, 8 minutes.
Spread each tortilla with 1 tablespoon of the Eggplant-Ancho spread. Add the tofu and vegetables, fold up the tacos and serve.
