The biggest thing to remember is that a manager is a servant of the team. Never the other way around. You enable them to do work. Which means handling information, communicating, helping them communicate, talking to management, protecting them from unreasonableness, setting clear goals, going to pick up the dang pizza yourself so the work doesn't stop, making sure there are long stretches of time to do work,etc. You do more grunt work than anybody and in return leadership happens.
