You have a low IELTS score of 5 band and I will request you to retake you IELTS again and score 6.5 band overall with not less than 6 band in each module. GRE scores could be useful in particular UK University but not mandatory required by most of them. You have failed to mention your B.Tech grades for me to suggest possible UK universities. I will suggest you to check University of Birmingham, University of Greenwich, University of Abertay Dundee, and University of Stratclyde. Visit more PG Computer Science courses offered in the UK.

It would be appreciated if you can provide your English marks in your 12th standard and first year of your bachelors. If, your marks are about 60% to 65% then you can enter into most of the modern universities like Robert Gordon University, Leeds Metropolitan University, Bedfordshire University, University of Greenwich, Anglia Ruskin University and you can find many more universities in UK which offer you the PG Computer Science program.

You need to choose your course and the collect your academic document "10th & 12th mark sheet, bachelors mark sheet & certificates, 2 reference letter, statement of purpose, passport, resume & if you have work experience then you can include the same but it's not mandatory. 

Apply to the university, once you get the offer letter pay the fees. You will get CAS letter, were you can apply for the VISA.
