In a medium bowl, mix graham cracker crumbs, melted coconut oil, and 1 tablespoon maple syrup.
Press the graham cracker mixture evenly into the bottom of the pan to form a crust. Bake for 8 to 10 minutes until lightly golden, then remove from oven and let cool for 10 minutes.
In a blender, combine the tofu, soy milk, coconut cream, lime juice, zest, the remaining maple syrup, vanilla, cornstarch, and salt.
Blend until completely smooth.
Pour the filling over the crust. Bake for 25 to 30 minutes, or until the center is mostly set and barely jiggles.
Let cool for 30 minutes, cover, then refrigerate for at least 4 hours (or overnight) until fully firm.
Cut into bars and garnish with fresh lime slices and zest.
