Hopefully some pike experts like Esox will chime in here.
I haven’t fished for them much, but have caught a few accidentally fisjhing for other stuff. But I think some basic pike flies would be large streamer patterns that cover different layers of the water column. Typical pike colors tend to be black, chartreuse, and white, and patterns based around predominate baitfish—perch looking patterns for example.
Examples would be Dahlberg Divers, cone head rabbit strip flies, mega divers, and large salt water type lefty deceivers. A frog looking surface thing would be fun to throw too around weeds in summer I would think. I’d try keeping most of the flies around 2/0 or so to be able to throw them with your 8 weight.
A big part of the game is finding them based on tehir seasonal movements. This book, “Mastering Pike on the Fly” by Barry Reynolds might be a good resource for you (although new ones are out of stock it looks like you could pick up one from another vendor for about 13 bucks.) It goes into some detail on patterning pike by season, how to fish different types of lakes etc as well as gear, flies, and different presentations

Hopefully some of our pike experts will weigh in too--- if they're not out chasing them.
