Displaying blog roll in template

I hope someone can help.
I am currently using the studio theme but I have a need to display one of the categories in a differently styled page (not the studio theme). I have created the template to display the category in a list fashion, and it works how I want it to.
However, when I click on one of the links it displays the post in the studio theme.
Is there a way I can have it so that the list will display within the same page, or a differently styled page?
I'm not seeing how to do that. I think I have been looking at it to long and need a fresh pair of eyes.
thanks...here is the code minus the styling have on the real page:


<?php if($bp_existed == 'true') : ?>
<?php do_action( 'bp_before_blog_page' ) ?>
<?php endif ?>
<div class="page" id="blog-page"><!-- start #blog-page -->

<?php wp_list_categories('include=3&title_li=<h2 class="teal">' . __('Recipe Index') . '</h2>' ); ?>

<?php wp_list_categories('orderby=id&show_count=1&use_desc_for_title=0&child_of=3&title_li='); ?>
