Hi Flower,
My immediate response would include:
* Lead by example, modelling best practice
* Develop good communication channels between you and your team, and within the team
* Support and develop individual practitioners through getting to know their strengths and areas for development, give praise and thanks for a job well done
* Be an active listener and treat everyone fairly and equally
* Learn to delegate (not to offload work, but to use the skills of your team in an appropriate way)
How will you know that you're effective?
* Get feedback from your team to find out what they think about your leadership
* Do things get done properly and on time?
* Is time management handled well by everyone?
* Is the team happy and committed?
I'm sure others will be along with their ideas soon
