Answer
Wa alaikum assalaam wa rahmatullahi wa barakatuh,
This is not uncommon, especially in the mudood letters.  On the whole this mistake is not too difficult to fix by Allah's will, but of course needs work from the student along with dua'. 
 If you have it all of your letters, it may take a bit more patience and steadfastness to overcome the problem, but it can be done with Allah's help and striving. Usually those who have a ghunnah in all their reading also have a strong nasalization in their speech. 

The first step in trying to correct it is to train your ear to hear it.  This can be done by forcing the incorrect nasalization on a letter, for example by elongating a medd letter and then forcing a ghunnah in it by letting the air flow purposely up through and out the nose, then trying to correct that and force the air out the mouth.  After doing this 5 or 6 times, insha' Allah you will start to feel and hear the difference between the incorrect ghunnah with the and the correct sound coming out solely from the mouth.  This practice then can be extended to the other letters which are coming out incorrectly with a ghunnah.   After several sessions like this, you can start testing your reading by pinching off your nose when you are reading the letters which have the problem and seeing if the sound diminishes.  If the sound diminishes when you pinch off your nose while reading, there is a ghunnah there. 
If you find there is a ghunnah, go back to the first exercise again until you are sure you can control the flow of the sound so it all goes out your mouth when there is no ghunnah wanted in the reading.  
This error is generally not fixed in a day or two, but with Allah's help it should not be too hard. 
May Allah make it easy for you. 
Wa iyyaakum.
