Information on the proportion of teachers by gender is available from the Database of Teacher Records which is collected primarily for pensions administration purposes. Figures from this source are not considered sufficiently reliable to publish at the local authority level.
The information requested is available for England and has been published in table D2 of the School Workforce Statistical First Release, January 2007 (Revised) at the following web link:

The School Workforce Census planned for 2010 will provide more detailed information on the school workforce at local authority level.
