Here are few quick, concrete suggestions:
Get to know your team as individuals. What motivates them? Do those things more. What de-motivates them? Don't do those things. People respond very well to leadership and management when they feel like you know them and act like you care.
Say "thank you." And mean it. More than financial rewards or taking the guys out for beers, humans like to be recognized and thanked for their hard work. Jack Welch, legendary CEO of GE was awesome at this. Send a thank you note or thank individuals in front of others.
Set clear expectations. Ask the team what is expected of you, and exceed those expectations. When a team respects your work, you can be demanding of them, and they won't think twice about doing good work.
Be human. Acknowledge the human elements of a team/project while being practical about the business' needs. Admit when you make a mistake. Don't punish others for their mistakes. Always focus on the positives and what can the team do to move forward. Say things like, "I'm really sorry, I screwed ABC up. What do you guys think about this plan to move forward with XYZ?" Or, "I know it sucks that the company decided blah, but we have an opportunity to help the bottom line and look good doing it."
Don't waste people's time. Do standup meetings if your methodology calls for them, but only if they add value to the project.
I know these are all over the place. As others have pointed out, there's a lot that goes into being a good leader, but these are a few things I have put into practice that have really helped.
