I agree with the above - in Reception main focus is on reading - keep reading with her and to her. Get extra reading books at the library, if school doesn't provide enough, or for hollidays. Also - anything that enriches her understanding of the world around her is great. If she is not yet - try to get her interested in non-fiction books as well as fiction.
If/when you decide to give her extra practice - look at these workbooks. For Math, specifically, I like them better than Bond papers. My DD loves math and we've used these since Reception both to give her some extra stimulation and as we prepared for 7+ this year.

I wouldn't worry about English and Reasoning papers until sometime in Year 1.
As her writing skills develop - you can get her to practice it more by doing little projects at home - show and tell for school, or writing a diary/scrapbook. Mine was/is a reluctant writer, so on holidays we always try to keep a diary with pictures, etc.
Story writing is also something that they always have at 7+ and that is not taught extensively in R-Y1-Y2. Not even at a private school that my DD is at as our school is working towards 11+, not 7+. So, when later your daughter starts doing spellings for school and will have to write sentences with the words, get her to think about making up a little story with these words. We started doing it in the Spring term in Y1 and continued at Y2.
Generally, I think, if you have a bright and curious kid, and is open to you doing a little extra with her starting at Reception, she'll be a happy and confident student, and getting her ready for 7+ won't have to be stressfull.
