So first things first,
- Set some process - I know this sounds formal but let me tell you, If there is no process you are not bound to anything. I think there needs to be basic rule sets which has to be followed everyday. Without that, things cascade and results to delay.
- Track your progress everyday - We need to keep a check on what we're working right now, where is the project heading to, how close are we to the completion.
- Break a big task to fewer tasks and Actively move them on your board - This happens almost everywhere and not only in remote jobs. Ask your remote reviewer to view the board and ask him to provide comments on every task's completion.
Now, the last and the most important.
- Inform every move - Don't shade away with anything. Always keep in touch, conduct and attend meetings. Even if it is the simplest of the simplest things, inform. This way you will feel connected and motivated to work.
