Well, those are some pretty big questions.
1) All of a sudden removing the pages from site, will it make my site small under Google Eye.
How many pages will you remove? How many pages will you have left on your site after you remove them?
2) What are the SEO effects will my site be facing after removing the pages
For the pages you want to remove, what percentage of traffic do they get?
What will you do with those pages once you remove them?
3) How should I go with this issues smoothly without effecting my website.
If you will put those pages on a different website, then you should set up 301 redirects to those pages.
If you DON'T put those pages on a different site, that is fine. You just want to 401 those pages that will be removed. Just let google see that they no longer exist.
I hope this helps.
