Convert pagination to Wordpress

Hi,
I am looking to recreate the pagination on this page:

As you can see - I want to - as I'm creating a HTML to WP conversion to make those paginations actual real links. The pagination to the left (if it's still there when you check) is a real link. Here's my issue - I want to know how I can do this - whether with a built in Wordpress function or a custom function.

Note: this is in the home.php page template (for blogs) and you can see the source code below:
