If Harry was replaced with a deer, his grace and speed could play a big role. In the Triwizard Tournament, instead of using magic to get through the tasks, he could use his deer - like abilities. He could jump over obstacles and run really fast. And in the face of danger, like when Voldemort is around, he could use his ability to blend into the forest, since deer are good at camouflage in their natural habitats. This would completely shift the way battles and challenges are faced in the story.

Also, the way he approaches challenges would be different. Instead of using magic wands and spells, he might rely on his animal instincts like a strong sense of smell to track down things. This could lead to different solutions for the mysteries in the story.
Let's say Harry was a raven. Ravens are often associated with mystery and intelligence. A raven - Harry would be able to fly around Hogwarts and spy on the bad guys more easily. His communication might be in caws and clicks which could be a code that only certain people or animals in the wizarding world could understand. The plot would then revolve around decoding his messages and using his unique perspective from the air to uncover secrets. For example, he could discover hidden passages or the whereabouts of Horcruxes by observing from above.
