Lesson plans are great, but we should all be allowed to plan in our own way. The lesson plan should be a note to ourself, not instructions for how anyone could teach it and why, which is so time consuming.
A good manager would let you submit your lesson plan in any format you like, and occasionally come by, with it printed out, and ask you to explain what you did, how you did it, what worked and didn't work.
They aren't checking these things, they are just looking in a folder and counting that they are there. Opportunity cost is something my managers are unaware of. Writing a step by step lesson plan with links to files and blah, blah, blah is all time I'm not spending actually developing those resources.
