The theme of trust often pops up. Given their different natures, building trust between Bishamon and Yato can be a central plot point. Also, there's the theme of sacrifice. In some fanfictions, one of them might be in a situation where they have to sacrifice something for the other's sake.
Another setting might be during a festival. There are bright lights, happy people all around, and a festive mood in the air.

One common theme is the exploration of their complex relationship. Given their history in the original work, fanfictions often delve into how they might overcome their differences and develop a deeper bond. Another theme could be adventure, where they team up against common enemies.
The general plot of a bishamon x yato lemon fanfic often centers around the relationship between these two characters from Noragami. It could be that they start off as adversaries or at least have some sort of conflict. But as the story unfolds, feelings start to develop. The 'lemon' aspect comes in when the relationship becomes more physical. For example, there could be a scenario where they are forced to work together on a mission and that proximity leads to a deeper connection and eventually the more adult - themed interactions. But it's important to note that this is a very broad generalization and different fanfics will have different takes on it.

One interesting crossover could be a story where Naruto's world is invaded by ayakashi from the Noragami universe. Naruto and his friends have to team up with Bishamon's shinki. They would learn about each other's powers and cultures. For example, Naruto's ninjutsu might be a mystery to the Noragami characters, while the concept of shinki could be new to Naruto.
Naruto has the power of the Nine - Tails, which is a huge source of chakra. Bishamon has her own reservoir of divine power. In a fanfiction, they could combine their powers by having Naruto transfer some of his chakra to Bishamon, who then uses it to supercharge her attacks. Or vice versa, Bishamon could bestow some of her divine essence on Naruto, allowing him to access new forms or abilities that are a blend of both ninja and divine powers.
