I worked for multiple companies remotely and the thing that worked the best for me was:
- Everyone must be connected to Discord in an audio room. - Encourage pair programming. - Record every meeting make them available to everyone. - Log every decision in a central place, easy to browse and discover. - Meet regularly (IRL) with you colleagues.
By far the most important point is always being on Discord. You can quicky jump in someone's room and feel very connected to your teammates. Obviously, like in a real office, don't disturb someone if it can be managed asynchronously.
