The first thing you need to do is decide what you want to do. Do you want to be a manager? If not, you need to go to your VP and tell him to hire someone to manage so you have time for the technical side. If you want to be a manager then you need to delegate most of the technical stuff. Not necessarily at the architecture level, but you really shouldn't be doing things like coding or writing estimates. You may be good at that kind of stuff, but other people are good at that kind of stuff too. Hire one of them. The worst managers are the ones who can't let go of the technical work and half-ass the important part of their job, which is to manage.
