There are a number of companies that are extremely successful at working fully remotely like InVision or Zapier, and one great thing they share is that they've actually done "manuals" on remote work. Check this out for example: https://zapier.com/learn/remote-work/ .
One thing many people will tell you is the importance of over-sharing. Try to share as much as possible and have ways of doing it. Besides the typical Slack, Zoom or Trello to work remotely I highly suggest you check out Mural.co for design teams.
