It sounds like you haven't given up your ownership of the code. If you're leading a team of 8-12 people and don't have time to do any coding by yourself, you no longer own the code, your team does. You are going to have to let go of your personal coding responsibilities and understand that there are always multiple solutions to problems. The solution members of your team use may differ from the solutions you would have chosen AND THAT'S OK. The most you should be doing is architecting a general solution for projects but leaving the actual implementation to your team. Depending on the complexity of these projects, your time may be better spent documenting/diagramming processes, improving specs/requirements.
