Believe it or not, they actually prefer a bare hook. And it has to be a red colored hook. My variation on the single hook is to tie two hooks as close together as possible. It's actually my favorite setup. I think it gives a little more profile and entices a few more bites.
Sockeye salmon tend to stratify in the lake during different times in the morning.
When there is still low light, just before 5 a.m., you can catch them between 25 and 30 feet deep. As the sun rises, they head deeper. They're not like chinook or coho salmon, where you may find them at all levels. Once you get into some fish, they're usually within 5 feet up or down. So depth control is really important.
