A theme might be the transformation. For example, in some fanfictions, Sakura or Hinata could be turned into vampires. This would bring a whole new dynamic to their relationships. They would have to adapt to their new powers and instincts. Also, loyalty is often a theme. Naruto and Sasuke, as vampires, would have to prove their loyalty to their human partners, especially when faced with the vampire community's rules and their own dark desires.
One common theme could be the struggle between human and vampire nature. In Sasusaku and Naruhina scenarios within vampire fanfiction, Sasuke and Naruto might be vampires while Sakura and Hinata are humans. The stories could revolve around the vampires' attempts to control their bloodlust in the presence of their beloved humans. Another theme could be the idea of forbidden love. Since vampires are often seen as different and dangerous, their relationships with humans are not always accepted, creating a lot of drama and tension.
Self - discovery is a big theme too. When the characters are thrown into different time periods, they learn more about themselves.

In Naruhina vampire fanfiction, Naruto could be a more outgoing vampire, and Hinata might be shy but intrigued by him. Their relationship could develop as Naruto protects Hinata from other vampires or from the human world's ignorance about vampires.
The theme of sacrifice is also prevalent. In many of these fanfictions, either Sasuke or Sakura might have to sacrifice something, like their normal life or certain beliefs, in order to be together as vampire mates. It adds a lot of depth to the story.
One common theme is the power struggle. Sakura, as a vampire hunter, is constantly in a power struggle with the vampires. And Sasuke often has his own power - related issues, whether it's his own strength or some hidden power. Another theme is the forbidden love aspect. Since Sakura is a hunter and Sasuke may have some sort of connection to the vampires, their relationship is often seen as forbidden.
