1 - "Number of programs planned to apply to: around 10" - It seems a low number to me. Not too low, but competition for PhD programs in marketing can be fierce, and you probably can find more than 10 schools that would be a good fit.
2 - "I want to have a career in academia." - Well, this is like stating the obvious. If you don't want to have a career in academia, you probably shouldn't be applying to a PhD in business anyway. This tells us nothing about your motivation. I know this is just a post here, but be sure that you have a much better answer for that question when you write your Statement of Purpose. Faculty want to see strong, specific reasons.
3 - There is a lot of things that look quantitative stuff in your profile ("168Q", "Business Analytics", "Statistics and Decision Modeling", "Economics"). You may be asked, or faculty may wonder, why you are applying to Consumer Behavior, and not Quantitative Marketing, for example. So, you'd better be ready to explain that too.
4 - "I did not have a strong academic background in Marketing or any research experience in this field." - For marketing PhD, I think it's actually rare to see people who have a background in marketing. For Consumer Behavior, you see people with a background in fields like psychology, and sociology. For Quantitative Marketing, you see things like economic, and engineering. But there is room in Marketing PhD programs for philosophy, arts, chemistry, journalism, architecture, computer science, among other fields. So, lack of background in marketing is not an issue. For Consumer Behavior, I think it's actually better a background in Psychology than in Marketing, for example.
5 - "What are the chances that I will get into one of the top 100 Ph.D. business program?" - Your profile seems to be quite strong to me. Not a bad GRE and GPA. Research, teaching, and work experience. Even a paper published. You have a lot more than many applicants. I'm actually kinda surprised to see you asking about top 100, and not top 50, for example.
6 - "What can I do until the next application round to improve my profile?" - Your profile seems strong, but unfocused, vague. This makes it hard to see what you should do. I don't even know your topic of interest. At least that's the feeling I got. If you didn't tell me that you intend to Consumer Behavior, I don't think I would ever guess it. So, I'm not sure what you have to show schools that you are really a Consumer Behavior applicant, that CB is really your thing, that you are passionate, motivated, and certain about it. If you have those things, you should highlight them, because right now we need to look hard to find something. At very least, you should work on your strategy. to make you look you are the right person, in the right concentration, for the right advisor, in the right program.
