Muslims Face Mecca for Prayer When Muslims pray, they face Ka'bah which is in Mecca.
Think about the ancient times. Slaves used to bow and some used to prostrate their kings (such as Pharaoh). One bows before someone to express his/her respect. Or some bowed and prostrated some others among them as if they were god.
Worshiping is our first job. We are the slaves of Allah. As it is said in Holy Quran: "I didn't create Jinns and human-being, except for worshiping Me". We must worship only Him. We express our worship in the form as we call it Salat-Prayer. And bowing and prostrating should be only towards the God Almighty. But where is He? To which direction should we face while praying? And Allah ordered his Messenger (Muhammad PBUH) to face to Ka'bah while praying. It is like you worship Me and pray unto Me facing to Ka'bah.
The Qur'an says (2:144 and after)
We have seen you turn your face to the heavens. We shall turn you to a Qiblah that will please you. So turn towards the Holy Mosque (Kaaba), and turn towards it wherever you be. And those who are recipients of the Book (Jews and Christians) surely know that this is the truth from their Lord; and God is not negligent of all that you do. (2:144)
Change of the Qibla from Jerusalem (Bayt al-Maqdis) to Mecca (Ka'ba)
When the Prophet (peace and blessings of Allaah be upon him) came from Makkah to Madeenah, he used to face Bayt al-Maqdis when he prayed, and that remained the case for sixteen or seventeen months, as is proven in the two Saheehs (al-Bukhaari and Muslim), in the hadeeth of al-Baraa' ibn 'Aazib (may Allaah be pleased with him and his father), who said: "The Prophet (peace and blessings of Allaah be upon him) prayed towards Bayt al-Maqdis for sixteen or seventeen months, and he was hoping that the Qiblah would be towards the House (i.e., the Ka'bah)…" Then after that Allaah commanded him to face the direction of the Ka'bah (the Sacred House), in the aayah (interpretation of the meaning): "… so turn your face in the direction of al-Masjid al-Haraam (at Makkah). And wheresoever you people are, turn your faces (in prayer) in that direction…" [al-Baqarah 2:144].
Before we answer the question about the wisdom behind this change, we must note the following points:
Note 2
Muslims face Mecca when they pray because they believe that that was where the first shrine was built.
Note 3
Facing towards Ka'bah doesn't mean that Allah is there. Allah accepts our prayers while we are facing to Ka'bah. And also we don't worship Ka'bah, we worship Allah facing towards the Ka'bah.
Note 4
And also before being the qiblah of Ka'bah, Prophet Muhammad PBUH used to face to the sky while praying, then it is commanded to Him PBUH to face the Ka'bah while praying
Note 5
When Islam's founder - Ubu'l Kassim aka Muhammad first started, he wanted to pray to what he thought was the most holy city - he used to face Jerusalem, then after he became leader of Medina, he tried to convert the Jews and could not, that's when he started facing Mecca instead and that's also when he started treated Jews poorly.

The Qiblah, for any point of reference on the Earth, is the direction of the Kaaba. In Muslim religious practice, supplicants must face this direction in prayer.
