i have created a custom post type which has 2 custom upload

Hi, i have created a custom post type which has 2 custom upload fields one is a document (pdf or docx) and one is an audio file (mp3). I want to display these custom fields in my custom post using the google doc embed shortcode and the wp audio shortcode. I have created a template file for this custom post type and want to hardcode this into the php template file using php do shortcode etc and pass the custom fields as variables to these shortcodes. How do I do it?

Thanks in advance.
