We homeschool our two kids for two years now, because both had made bad experiences in the conventional school system.
It took us a while to find our pace, but it is going very well so far. There is plenty of homeschooling material out there plus a rising number of distance learning curricula that you can pick from.
I recommend that you take a look at the school curriculum of the high school that your child will potentially join and work backwards from there. For the most part, prerequisites will boil down to language comprehension, as well as science and math :)
You as instructor will have to prepare though. We have workbooks for grammar and math, but we let them choose what books they want to read. We also have science material, like electronics kits, geologic samples, microscope, models of the human body, a few apps for geography, etc. Once a week, they meet with a private tutor.
We do not have a fixed schedule, because both kids do a lot of sports and we want to let them play and roam when they're in the mood. We usually let them chose when to work on something but require school work before screen time. We also use a point system where they receive a sticker for each completed task. When they're done with a month worth of stickers, they can pick something small from the toy store, but the stickers also help them to see what they've accomplished.
This is what worked for us, but I recommend that you try out different strategies and see what works best for you and your child. Becoming a home teacher can be a challenge, because you'll have to help your kid cross that motivational barrier quite so often and that will naturally result in conflict. Just keep in mind that the relationship to your child is more important than whether you achieved all of your daily schooling targets.
Good luck!
