Preheat the oven to 425 degrees F. Blend the tofu in a food processor until smooth. Add the confectioners' sugar, cream cheese, flour and vanilla and puree until combined.
Stack the phyllo sheets on a flat surface and cover with a slightly damp kitchen towel. Cut a piece of parchment paper slightly longer than the phyllo. Lay 1 sheet phyllo on the parchment with a long side facing you (keep the remaining phyllo covered). Brush with 1 tablespoon butter and sprinkle with 1 tablespoon graham cracker crumbs. Top with another sheet of phyllo, then more butter and crumbs. Repeat with the remaining phyllo sheets, topping each with butter and crumbs. Reserve the remaining butter and crumbs for topping.
Spoon the tofu mixture across the length of the phyllo, leaving a 1-inch border at the long edge closest to you and a 2-inch border at the short ends. Sprinkle the raspberries on top of the tofu mixture. Starting with the long edge, use the parchment to roll the phyllo tightly over the filling to make a log; turn seam-side down on the parchment. Brush with the remaining butter and sprinkle with the remaining crumbs.
Transfer the parchment and strudel to a baking sheet. Bake until golden, about 18 minutes, rotating the baking sheet halfway through. Slide the strudel onto a cutting board and let cool completely, about 1 hour. Dust with confectioners' sugar.
