I am from Pakistan and have a friend (Philippine's citizen) living in Macau.

You need to find a company to employ you and then the employer can get you the relevant documents to apply for the work entry permit, so if you haven’t found a job, you cannot apply for a work entry permit.
When you want to apply for a tourist entry permit, you need to provide those documents including copy of your passport, the application form, a passport-style photo, proof of your financial support, transportation and accommodation arrangement, an invitation letter from your friend. And then you can ask your friend to submit the application to Macau immigration department to apply for the tourist entry permit, or you can just submit the application to the embassy of PRC to apply for it.
