Unless your articles require all members/shareholder to be directors you have given away your right to be a director, as for practical purposes with 2 v 1, they could exclude you, and outvote you.
Your rights exist under section 20 to be consulted and ultimately to challenge what they propose, but as long as that is correctly done and the proposals are fair and reasonable in scope and cost, permitted under the lease, then you have to accept them.
The only question I have is you say you bought the freehold and then set up a company.
If the company did not acquire the freehold, ( which means that you jointly own the freehold) what authority has that company to do anything?
Based on the information posted, I offer my thoughts.Any action you then take is your liability. While commending individual effort, there is no substitute for a thorough review of documents and facts by paid for professional advisers
