I’m trying to recreate a similar art style to games like Yooka Laylee: Image or Snake Pass: Image
How would I go about creating that lighting/ post processing that these games have?

It’s not exactly the same style but it should be a good start in the right direction and the content covers all the necessary elements to create what you are trying to achieve. This will also help as well:
