There could many reasons why your website traffic gone down, but as far as theme changing is concerned i don’t think that it plays a huge role in traffic.
But it plays huge role in user engagement. if you want to find out the reason, you should revise SEO of your website back and compare the things when you had your old theme live with new one. you would find something to work on..
And please check out that your site is not hit by Panda, because Google recently enrolled it….
