I used to do a fair amount - haven't been hiking/camping in a while though. When I did do it the ultralight backpacking guides on the web proved very useful especially as I usually carry too much anyway.
it's an old list but 3 day, 3 season with only 7.5kg of gear and consumables

check out google and a book called "
beyond backpacking" by
ray jardine - it's a lot verbose but covers everything you need. There are even has the patterns for his bags and gear for you to download if you care to sew your own.
He does know what he's talking about. He founded and sold
Golite based on his ideas.
