You should recite (in ARABIC) on a regular basis:

1) Al - Fatiha
In the name of Allah, the Beneficent, the Merciful
Praise be to Allah, Lord of the Worlds, (2) The Beneficent, the Merciful. (3) Owner of the Day of Judgment, (4) Thee (alone) we worship; Thee (alone) we ask for help. (5) Show us the straight path, (6) The path of those whom Thou hast favoured. Not (the path) of those who earn Thine anger nor of those who go astray. (7)

Al-Ikhlas

Say: He is Allah, the One! (1) Allah, the eternally Besought of all! (2) He begetteth not nor was begotten. (3) And there is none comparable unto Him. (4)

Al-Falaq
In the name of Allah, the Beneficent, the Merciful
Say: I seek refuge in the Lord of the Daybreak (1) From the evil of that which He created; (2) From the evil of the darkness when it is intense, (3) And from the evil of malignant witchcraft, (4) And from the evil of the envier when he envieth. (5)

An-Nas
In the name of Allah, the Beneficent, the Merciful
Say: I seek refuge in the Lord of mankind, (1) The King of mankind, (2) The God of mankind, (3) From the evil of the sneaking whisperer, (4) Who whispereth in the hearts of mankind, (5) Of the jinn and of mankind. (6)
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
3) Ayat al Kursi (i.e., Al - Baqarah: 255)
Allah! There is no God save Him, the Alive, the Eternal. Neither slumber nor sleep overtaketh Him. Unto Him belongeth whatsoever is in the heavens and whatsoever is in the earth. Who is he that intercedeth with Him save by His leave? He knoweth that which is in front of them and that which is behind them, while they encompass nothing of His knowledge save what He will. His throne includeth the heavens and the earth, and He is never weary of preserving them. He is the Sublime, the Tremendous.

Repeat the following du'a's on a regular basis both in the morning and evening three times or more:

Bismillahi alladhi la yadurru ma a ismihi shay'un fi al ardi wa la fi as sama'i wa huwa as sami 'u al 'alim
In the Name of Allah; with His Name, nothing whatsoever on earth or heaven can inflict any harm;
He is All - Hearing and All - Knowing...

Hasbiya Allahu la ilaha illa huwa alayhi tawakkaltu wahuwa rabbu al- 'arshi al- 'azhim
Allah suffices me; there is no god but He: in Him i place my sole trust; He is the Lord of the Mighty Throne.

Allahumma inni a oozu bika min hamazaa tis ash shaytan wa a 'udu bika rabbi an yahduran
O Allah i seek refuge in you from the whisperings of satan; my Lord, i seek refuge in you from their presence around me.

A'udhu bi 'izzati Allahi wa qudratihi mimma ajidu wa uhadhiru
I seek refuge in Allah's glory and power from the affliction and pain i experience and suffer from.

*It is important to remember that du'a and dhikr will only benefit when it comes from the heart that firmly believes in Allah,
