Upcoming parental leave as a leader. Need help!

I'm gearing up for parental leave next month and trying to build a comprehensive plan for my team of 5 while I'm out. I will be out for 18 weeks and I've only been in my current role for about 90 days. I've started to get everything organized but have not found any solid examples of what a plan should look like for someone in a leadership position. I want to be as thorough as possible since my boss sits in a different location and my team will be acting fairly independently. Any resources or advice would be very much appreciated!
