If you have been in Software Development for a long time, then you surely have got strong skills. I am not sure why you want to change your career but here are some jobs you can consider. You can get into management (project manager, department manager), you can build a start-up. By building a start-up you will be teaching a lot to young developers. I know that with start-up, you need time to start getting good profits and setting it up is too much work. But hey, if you need a career change then you need to do this.
