Was the rest of the team local to each other? That can be difficult because the team may be accustom to conducting all communication verbally, where you need it to be electronic. I was a new-comer to the team when I became the remote lead, and one of the things I did was focus on getting folks to communicate electronically. Luckily for me, they were in individual offices spread around the building and two were in other buildings, so they were already using IM, chat, and email. I just needed to reinforce it.
Also from the beginning, I've focused on team cohesion and team communication. The team was in a bad state when I joined, so again lucky for me, it was something I knew needed extra attention. As a team lead, it's an important factor that you need to pay attention to, but perhaps don't have to spend a lot of time on when everyone is local. As a remote team lead, you need to spend a non-trivial amount of time on it.
And face time is still important. I travel twice a month for a day or two and try to meet with everyone during that time. I also conduct a daily standup where the rest of the team is in the room and I'm on the phone. It can be difficult to follow the conversations in the room from the phone, but really the goal is to make sure the team is talking to each other, and isn't about my control of the conversation or of the team.
Where in FL are you?
