A notable 'Warhammer Fantasy Lizardmen' novel is 'The Plague and the Lizardmen'. In this novel, it shows how the Lizardmen face the threat of a plague that is spreading across the land. It details their attempts to combat it using their ancient magic and the strength of their warriors. It also delves into how they interact with other races during this crisis.
Well, 'The Rise of the Saurus' is an interesting 'Warhammer Fantasy Lizardmen' novel. It focuses on the Saurus warriors, their training, and their role in the Lizardmen society. It gives a detailed look at their combat capabilities and their loyalty to the Old Ones. There's also 'Lizardmen and the Great Cataclysm' which shows how the Lizardmen dealt with a major cataclysmic event in the Warhammer Fantasy world.
One main theme is the connection to the Old Ones. The Lizardmen are deeply tied to their creators, the Old Ones, and this is often explored in the novels. Another theme is their struggle for survival against various threats in the Warhammer Fantasy world.
First, study the existing Lizardmen lore. Know their traits like their loyalty to the Slann, their combat abilities, and their hierarchical society. For a crossover, find a way to contrast or combine these traits with the new elements. For example, if crossing with a race that values individualism, how would a Lizardman, used to a strict hierarchy, react? Second, give them personal goals within the crossover story. Maybe a Lizardman wants to learn from the new world's magic to better serve his race.
The 'Grey Seer' series is also quite good. These novels offer a deep look into the Skaven society. You'll see how the different castes interact, from the lowliest slaves to the powerful Grey Seers, and how they plot to gain power and dominate the world.
The 'Warhammer Fantasy Gotrek Novels' are known for their dark and gritty atmosphere. 'Skavenslayer' is another notable one. In this novel, Gotrek and Felix face the devious Skaven. The novel really delves into the nature of the Skaven race and the challenges our heroes must overcome. It has some really intense fight scenes and great character development for both Gotrek and Felix.
One of the popular ones is 'Nagash the Undead King'. It delves deep into the origin of vampires in the Warhammer Fantasy world. It shows how Nagash, a powerful necromancer, played a crucial role in the creation and evolution of vampires.
Another interesting read could be novels that touch on the battles against Nurgle's forces. For example, some stories where the forces of order fight against the pestilent hordes of Nurgle. These often show the contrast between the clean and orderly side and the decay and chaos that Nurgle represents. They also highlight the heroism of those who stand against his blight.
One idea could be to have the Lizardmen cross over with a modern-day military unit. The contrast between the primitive - yet highly advanced in their own way - Lizardmen and modern military technology would create interesting scenarios. For example, how would the Lizardmen react to firearms? Another could be a crossover with a fantasy world like Middle - earth. The Lizardmen's unique culture and magic could interact in fascinating ways with the races and magic of Middle - earth.
One great piece of lizardmen and human fanfiction is 'The Alliance of Two Races' on FanFiction.net. It tells a story of a young human and a lizardman who have to overcome their species' differences to save their shared land from a dark force. The story is full of adventure and the development of their friendship is really interesting.

There are a lot of different factions and characters involved, and the storylines are really engaging.
