One thing that may be helpful for teachers in an entirely digital environment is to have a framework off of which to build lessons. A group of teachers and edTech folks have put together several of these and called them #EduProtocols. These can be used for things like critical reading, collaboration, and communication.
Take a look:
You can find a curated list of several of these digital EduProtocols for various purposes on the following Google Sheet: https://docs.google.com/spreadsheets/d/1Ap9npeaFLtdJcqNApINrtjnawkWb0cGjlp0uECsoZo0/edit#gid=0
