Combine all of the cheese ingredients small saucepan. Whisk briskly continuously until the mixture comes to a small boil and starts to pull away from the sides of the pan. Remove it from the heat and transfer it to a small pyrex dish. Allow to chill and slightly set for about 20 minutes.
To prepare the rest
In a dry skillet, lightly toast the cumin seeds over medium heat for about 2 minutes. Set aside.
Add about a tablespoon of olive oil to the pan over medium heat. Add the slices of tempeh and saute until nicely browned, about 5 minutes for each side. Before removing the tempeh to cool, sprinkle with a few dashes of liquid smoke and drizzle with a little agave syrup.
Melt a little of the Earth Balance over a clean skillet. Place the bread on top and allow to toast for a few minutes. Flip it over, then spread some of the cheese over the top. Allow the other side to toast. Flip the bread over again so the cheese makes contact with the pan and slightly melts for 20 seconds or so. Remove from the pan.
To assemble the sandwich
Lay several pieces of the tempeh on the bread. Top with sauerkraut and sprinkle with the toasted cumin seeds. Top with the sriracha-Vegenaise dressing. Serve warm.
