One common theme is the forbidden love aspect. Since vampires are often seen as outsiders in the wizarding world, a relationship between a male vampire and a wizard or witch is usually considered taboo. Another theme is the power struggle. The vampire may have certain powers that are different from the magical abilities in the Harry Potter world, and how they interact or clash is often explored.
The theme of sacrifice is also quite common. In many of these fanfictions, the male vampire may have to sacrifice something, like his vampiric ways or his ties to the vampire community, for the sake of his relationship with his mate. And there's usually the overarching theme of how the two different worlds, the world of vampires and the world of Harry Potter, can coexist and how their relationship bridges that gap.
A prevalent theme is also the discovery of identity. The male vampire might be trying to find his place in the wizarding world while also dealing with his vampiric identity, and his relationship with his mate can play a big role in this. For example, his mate could help him accept his dual nature. Additionally, there's often a theme of protection. The vampire will go to great lengths to protect his mate from the dangers of both the wizarding and vampire worlds.
