For today's feast, I'd like to recommend St Joseph's website, where you can find prayers to the great foster-father of Jesus. If you need another recommendation, then according to the site, none other than St Teresa of Avila had this to say about him:
"I took St. Joseph for my patron and advocate, and I recommend myself unceasingly to his protection. I do not remember ever to have asked anything of him that I did not obtain.
It seems as though God gives to other saints the grace to assist us in some certain necessity; but according to my experience, St. Joseph assists us in every want. Our Lord, wishing to make us understand that, as He was obedient to His foster-father here upon earth, so He now can refuse no request in heaven. Many persons who have invoked him by advice have experienced this truth, and the number of his clients increases daily and corroborates what I declare.
For several years past, I have asked a special favour at his festival, and it has always been granted. If the request was not judicious, he has denied it for my greater good. I implore those who do not credit this to make the trial for themselves. Let him who has no guide in the way of prayer take this great Patriarch for his director. He will not go astray."
