How do I make change in job after 1 year of career break.

I previously worked as sales executive in prominent MNC and currently after 1 year of break preparing for CAT and also took medical break in this span, now I am interested in research analyst role in research reporting companies. How do I make shift in my resume and showcase it to the recruiter. I have average communication skills, but pro at making insight out of any article or research report. Company who's hiring leads will be appreciated
